O I can vouch for that .... No matter how much you use and abuse the bbm ... If you have a 6 gb plan you can never run out of it on bbm ... Hell I text like a person possessed .. And till date I have never even used a third of my 6 gb plan I use my phone for anything and everything under the sun 24*7*366 .... So just don't even bother my friend .... Just let it rip ..... And enjoy the wonders of bbm on your fav BB ...
